Three major faunal provinces of planktonic foraminifera were recognized along two North Atlantic crossings during the summer of 1962. The subarctic assemblage consisted of Globigerina pachyderma, G. bulloides, and G. quinqueloba; the transitional (temperate) fauna was characterized by Globorotalia inflata and mixtures of subarctic and subtropical species; and the subtropical fauna was composed of 16 species, typified by Globigerinoides ruber, G. sacculifer, and Globigerinella aequilateralis. Relative and absolute abundances for each species are mapped and some ecologic relationships are described.
